is a broad genre of Rock music popular music that originated as " rock and roll" in the United States in the early 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and in the United States. It has its roots in 1940s and 1950s rock and roll, a style which drew heavily on the genres of blues, rhythm and blues, and from country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical styles. Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass, drums, and one or more singers. Usually, rock is song-based music usually with a 4/4 time signature using a verse–chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political.
By the late 1960s "classic rock" period, a number of distinct rock music subgenres had emerged, including hybrids like
blues rock, folk rock, country rock, southern rock, raga rock, and jazz-rock, many of which contributed to the development of psychedelic rock, which was influenced by the countercultural psychedelic and hippie scene. New genres that emerged included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring subgenre of heavy metal, which emphasized volume, power, and speed. In the second half of the 1970s, punk rock reacted by producing stripped-down, energetic social and political critiques. Punk was an influence in the 1980s on new wave, post-punk and eventually alternative rock. From the 1990s alternative rock began to dominate rock music and break into the mainstream in the form of grunge, Britpop, and indie rock. Further fusion subgenres have since emerged, including pop punk, electronic rock, rap rock, and rap metal, as well as conscious attempts to revisit rock's history, including the garage rock/ post-punk and techno-pop revivals at the beginning of the 2000s.
were an Led Zeppelin English rock band that formed in 1968. Led Zeppelin consisted of Jimmy Page ( guitar), Robert Plant ( vocals), John Paul Jones ( bass guitar, keyboards) and John Bonham ( drums). With their heavy, guitar-driven sound, Led Zeppelin are regarded as one of the first heavy metal bands.  However, the band's individualistic style draws from many sources and transcends any one genre.  Their rock-infused interpretation of the  blues and folk genres also incorporated  rockabilly,  reggae,  soul,  funk,  classical, Celtic, Indian, Arabic, pop, Latin and country. The band did not release the popular songs from their albums as singles in the UK, as they preferred to develop the concept of album-oriented rock.
Close to 30 years after disbanding following Bonham's death in 1980, Led Zeppelin continue to be held in high regard for their artistic achievements, commercial success and broad influence. The band have sold more than 300 million albums worldwide,
    including 111.5 million sales in the  United States and they have had all of their original studio albums reach the U.S.  Top 10. Billboard Led Zeppelin are ranked No. 1 on  VH1's 100 Greatest Artists of Hard Rock.  magazine has described Led Zeppelin as "the heaviest band of all time" and "the biggest band of the 70s". Rolling Stone
On 10 December 2007 the surviving members of Led Zeppelin reunited (along with deceased drummer John Bonham's son
Jason) for the Ahmet Ertegün Tribute Concert at the O2 Arena in London.
